Traffic Safety Improvements at Low Water Crossings

The Texas Department of Transportation (TxDOT) Project 0-6992 "Traffic Safety Improvements at Low Water Crossings (LWCs)" proved how easy, low-cost countermeasures improve safety at LWCs by focusing on LWC delineation, using flood-detection sensors, and warning systems to alert travelers of flooded crossings. In addition to recommending the use of raised retroreflective pavement markers (RRPMs) to improve longitudinal markings at low-water crossings, the research team recommended experimenting with internally illuminated raised pavement markers (IRPMs) at problematic locations where drivers regularly drive through high water conditions. The research team will improve safety and operations at LWCs by incorporating a tool which integrates the National Oceanic and Atmospheric Administration (NOAA's) Multi-Radar/Multi-Sensor (MRMS) system, which combines radar, stream gauges, and environmental data to estimate rainfall rates with 1-kilometer resolution across the United States. By leveraging virtual sensor data, TxDOT will enhance the effectiveness of roadway flood warning systems, making early flood detection more robust and improving overall driver safety.
